Abstract

A strain of Actinomycetes producing cathepis B inhibitor was isolated from soil and identified as Streptomyces misakiensis. The product of S. misakiensis inhibited effectively cathepsis B proteinases as well as trypsin and papain. The cathepsin B inhibitor were largely produced with incubation for 4 days. The S. misakiensis was the most growth with incubation for 5 days. The cathepsin B inhibitor was isolated from the extraction of both with ethanol, ethanol and chlorofrom, and following several column chromatography such as sephadex G-15, silica gel 60 and sephadex LH-20 chromatography. The moleculer weight of purfied inhibitor was 138 dalton.
